Why is it OK to put something on your skin that you wouldn't eat?
This question struck me when I was teaching a childbirth class. One of the moms who was studying nutrition at Bastyr University said that rubbing olive oil in the skin is used to supplement the nutrition of patients in ICU who are tube fed. Apparently, the tube feedings can't contain as much fat as would be ideal, so they rub olive oil over the entire skin so it gets absorbed that way instead. (The topic came up because I was passing along the priceless tip to olive oil your newborn's butt so that the sticky meconium slides off...)
Until she told me this, it had never occurred to me that what is put on the skin has the potential to be used nutritionally by our bodies. It's made me re-think a lot of what I allow my skin to come into contact with.
I have absolutely no idea what % gets absorbed, whether different oils would make it through differently and would behave to your body exactly the same as if ingested.
Zone diet on and off for several years....worked, but too much focus on exact meal composition
